In a newly released report, federal regulators called the risk of cancer from Chinese-made Lumber Liquidators flooring low. Further details in the report cited health risks to be minor and temporary.

Last year, CBS’s "60 Minutes" reported that independent tests of the retail giant’s flooring found levels of cancer-causing formaldehyde to be off the charts, some close to 20 times above what’s allowed, based on California Air Resources Board (CARB) standards. The controversy has had implications for the entire building industry.

Although tests from the Centers for Disease Control and Prevention (CDC) showed some types of laminate flooring sold by Lumber Liquidators can cause irritation and breathing problems, the risk of cancer from exposure is low.

Lumber Liquidators' sales and shares were hammered after the CBS program "60 Minutes" reported in March last year that the laminates from China contained excessive levels of cancer-causing formaldehyde.

The CDC said customers who had installed the flooring and were concerned about formaldehyde should open windows for a few minutes every few days, use exhaust fans and avoid smoking tobacco in the home.
